BeerBox® F.A.Q.

MadeInUSABrewing Tools introduces the BeerBox®: the most innovative solution to home brewing in decades. It was conceived with portability and the average home refrigerator in mind. It was designed to be very portable and to fit easily in a home refrigerator or a cooler. And it is made in America. The BeerBox® can be used by homebrewers to store and carry your brews. With labels included, you can easily let everyone know the styles you have to drink. Watch this page for new innovations and tips about the BeerBox® and new products as we develop them.

The BeerBox® is great for storing your homebrewed cider, soda, kombucha and beer.


A few quick tips:

  • Your Choice: Carbonate in your BeerBox® or Transfer Carbonated Homebrew into your BeerBox® – click here for a longer description

    • Natural Carbonation: We encourage naturally carbonating your homebrew with priming sugar in your BeerBox®. When filling directly from a fermenter for secondary fermentation, simply fill using a hose just as you would when filling a keg or bottle, then cap with white gasket and faucet. The BeerBox® will expand, and round out while the pressure builds during the aging process/secondary fermentation, but don’t worry, it’s natural! When you chill it down the pressure will drop and the CO2 will help force your beer out. Don’t worry; the BeerBox® can handle some pressure.
        • Before your 1st pour – bleed off a little of the built up pressure or you may have beer everywhere! Depress the Schrader Valve to release some pressure.  It only takes a quick “shot” of CO2 to build the pressure back to keep the beer flowing freely and to keep it fresh for your next session.
    • Transfer from your Keg to the BeerBox®: Do not pour directly from your keg tap into the BeerBox® as you will end up with more foam than beer. If you have a keg system; connect one end of the hose provided to the liquid out, ball lock connecter and connect the other end of the hose to the BeerBox® using the hose adapter and force the beer into the BeerBox® via its faucet. BE SURE TO RELEASE PRESSURE IN THE BeerBox® BY DEPRESSING THE SCHRADER VALVE WHILE FILLING. Fill and go… very easy!
  • Use teflon tap (plumber’s tape) on the faucet threads when using the hose adaptor.  This will prevent leaks around the outside thread on the pour spout. The Teflon tape can be used on the outside threads before attaching the hose adapter. When the tap is opened to let the beer flow freely through the hose you get back pressure that may cause a leak around the threads.  The use of clamps with the hose is also encouraged to minimize leaks.  The 4′ hose, hose adapter and hose faucet are all included in the kit.
  • Don’t worry about the expansion, it is planned for in the design.
  • Using your CO2 Cartridges & Injector: When installing a new CO2 cartridge, screw the cartridge holder onto the injector head quickly and completely to minimize leakage of CO2.  And when your CO2 cartridge is spent, it may take some force to undo the cartridge due to the pressure created. Always discharge the CO2 completely using the trigger before attempting to remove the CO2 cartridge.

How many CO2 cartidges will I need to empty a BeerBox®?

To empty a BeerBox® it will take about 2 or 3 16 gram CO2 cartridges. It takes just a tap to get the beer flowing. Remember it is for dispensing purposes only.

What is the reason for CO2 if your naturally carbonating? Does it just keep it from going flat after you have essentially broke the seal by pouring yourself a delicious homebrew?

The thick, brown colored HDPE plastic is very low light and extremely low oxygen permeable.  The CO2 is used to compensate for volume lost as you pour your homebrew.  With no oxygen source a sort of vapor lock is created and no beer will flow.  A very short blast of CO2 will compensate allowing the beer to flow while keeping the beer fresh with CO2, unlike a screw/flip top growler. Fill your BeerBox® from your fermenter, add priming sugar for natural carbonation and let sit for 30 days.

How long does the beer typically stay carbonated if you are mainly using the carbonation of the beer itself mainly to dispense the beer?

We have users that report the beer remaining fresh and carbonated for over two months.  I have not been able to keep my beer around that long.  Because you are using CO2, via the injector, you are able to maintain pressure and carbonation over time.  There is no oxygen being allowed into the system, much like a keg, and the carbonation/CO2 does not get released as it does in a growler, so it stays fresh.

How does one measure the PSI?

I don’t usually worry too much about the PSI; much like bottling, it is what it is.  The BeerBox® will swell up when the beer begins to carbonate during the secondary process.  Don’t worry about it.  The BeerBox® is built to handle the pressure in spite of the 15 PSI rating.  If you really want to know the PSI you can use a tire gauge on the valve where the CO2 injector attaches.  It is a Shrader valve just like on your bike or car tire.

After you leave your BeerBox® at temp for 30 days, or whatever your secondary time frame is for the natural carbonation period and you chill it down to pour; if it is coming out too strong simply push the pin in on the Schrader valve and let off pressure.  You can always add more back in by attaching the CO2 injector and giving it just a very quick shot of CO2.  Be careful not to hold the trigger for more than a quick second and test the flow.  It is easy to give it too much gas and have your beer come out foamy.  It only takes a small amount of CO2 to get the beer flowing again; more as the beer volume decreases and the volume of are space inside increases.

Do you have a priming chart? How much priming sugar or DME should I use?

We don’t have a priming chart but here’s a link to a GREAT calculator for any kind of brewing sugar you might want to use. Courtesy of friends at Northern Brewer. For an overview about Carbonation, check out the blog post “Carbonation.”
